Description

Technical Field

[0001] The utility model relates to the technical field of liquid filling, in particular to a laundry detergent filling and capping system. Background Art

[0002] Filling machines are commonly used liquid packaging machines. Bottles of bottled laundry detergent are mostly irregular shapes with a handle on one side. The existing filling machines use cylinders to clamp the bottle body and fix the bottle when filling the bottle. Since most bottles are plastic bottles, the bottle body is made of soft plastic material. When positioning, the bottle body is squeezed and deformed, which makes the bottle mouth prone to tilt. Secondly, since laundry detergent is a viscous liquid, the laundry detergent adhered to the filling head will drip during filling. Once it drips onto the bottle body or the conveyor belt, it is more troublesome to clean. After filling, the staff needs to place the bottle caps on the bottle mouth in turn and align them, and then tighten the bottle caps through the capping machine. The low degree of automation increases the labor cost. At the same time, the existing capping device fixes the bottle by pressing the clamping plate at the front end of the cylinder. Since the bottle is irregular in shape, the clamping plate will squeeze the protruding part of the bottle when fixing it. After the bottle cap is tightened, it is in a sealed state. The squeezed part of the bottle will not rebound, affecting the integrity of the bottle shape. Utility Model Content

[0036] Preferably, a clamping plate 46 is provided on the piston rod of the bottle clamping cylinder 33 , a pair of movable pressing plates 47 are provided inside the clamping plate 46 , and elastic foam plates 51 connected to each other are provided inside the two movable pressing plates 47 .

[0037] The working mode of the filling device 200 is as follows: when the bottle is transported to the filling assembly position, the belt conveyor 20 stops, the bottle mouth clamping cylinder 24 starts to clamp the bottle mouth through the clamping claws to keep the position of the bottle fixed, and the filling head lifting cylinder 26 starts to drive the filling head 25 to extend downward into the bottle, and the valve of the filling head 25 is opened for filling. After the filling is completed, the filling head lifting cylinder 26 is reset, and the filling head 25 is moved out of the bottle mouth, and then the bottle mouth clamping cylinder 24 is reset to release the bottle mouth, and the belt conveyor 20 is started, and the filled bottle is moved to the next station. A photoelectric switch is provided on one side of the belt conveyor 20 at the filling assembly position. The height of the photoelectric switch is the same as the height of the bottle mouth, which is used to detect the position of the bottle mouth of the bottle, and the filling assembly is started according to the signal of the photoelectric switch.

[0038] In the present case, the receiving plate 28 is linked with one of the clamping claws of the bottle mouth clamping cylinder 24, and the receiving plate 28 moves in the opposite direction to the clamping claw, that is, when the bottle mouth clamping cylinder 24 clamps the bottle mouth, the receiving plate 28 swings to one side of the bottle mouth, so that the filling head 25 can move downward and extend into the bottle mouth. After the filling is completed, the filling head 25 moves out, and when the bottle mouth clamping cylinder 24 opens, the receiving plate 28 swings to the top of the bottle mouth, that is, directly below the filling head 25, to prevent liquid from dripping onto the bottle body or the conveyor.

[0039] A T-shaped mounting groove is provided on the top of the receiving plate 28 and runs through the front and back. The adsorption sponge layer is located in the groove, and the adsorption sponge layer can be quickly replaced according to actual needs.

[0040] The filling lifting seat 23 is used to adjust the height of the filling assembly to adapt to the height of the bottle. The adjustable protective plate 50 prevents the bottle from tipping over during the conveying process, and the spacing between the two protective plates 50 can be adjusted according to the model of the bottle.

[0041] The V-shaped bottle mouth positioning plate 27 is provided with an adjustment slot for adjusting the distance between the two V-shaped bottle mouth positioning plates 27 according to the type of the bottle.

[0042] The working mode of the capping device 300 is as follows: the filled bottles enter the second belt conveyor 30 through the bottle chute 35 . The bottle chute 35 is horizontal and has the same height as the first belt conveyor 20 and the second belt conveyor 30 .

[0043] When the material bottle enters the capping machine position, a pair of bottle clamping cylinders 33 clamp the two sides of the material bottle, and the capping motor 41 grabs the bottle cap and moves it downward to cover the bottle mouth of the material bottle. At the same time, the bottle cap positioning clamping cylinder 42 is started, and the positioning rollers on the clamping claws fit around the bottle cap to limit the surrounding of the bottle cap when the cap is screwed, and the capping motor 41 is started to tighten the bottle cap.

[0044] The belt conveyor 30 located on one side of the capping machine is provided with a photoelectric switch for controlling the capping machine and the bottle clamping cylinder 33 to start. The bottle cap vibrating loading tray 31 is used to arrange the bottle cap openings downward in sequence for output. In the specific implementation, the bottle cap fixing head 45 is a non-slip rubber fixing head to avoid slipping when the cap is screwed. The bottle cap fixing head 45 is provided with an air extraction hole, which is in the shape of a trumpet. One end of the air extraction hole is connected to a vacuum pump through a rotary joint. When the bottle cap fixing head 45 moves to the bottle cap at the discharge port of the bottle cap vibrating loading tray 31, the valve on the rotary joint opens, so that the bottom of the bottle cap fixing head 45 is in a negative pressure state to adsorb the bottle cap, so that the bottle cap fixing head 45 can move the bottle cap to the bottle mouth of the material bottle smoothly. The cross slide 43 is used to control the capping motor 41 to move up, down, left and right to perform bottle cap grabbing and installation actions.

[0045] The capping adjustment lifting seat 40 is a manual screw lifting seat, which is used to adjust the height of the entire capping machine according to the height of the bottle.

[0046] A pair of movable pressing plates 47 are installed symmetrically, and the movable pressing plates 47 are movably connected to the clamping plates 46 through springs. When clamping, the two movable pressing plates 47 can freely adjust their directions according to the shape of the bottle body. Combined with the elastic foam plate 51, the bottle body can be well fitted and fixed, effectively preventing local squeezing and depression of the bottle body during the clamping process.

[0047] In this case, the elastic foam board 51 is a pearl cotton foam board.

[0048] The bottle stopping and decelerating assembly is used to control the spacing between the bottles entering under the capping machine 32, so as to facilitate the bottle clamping cylinder 33 to clamp the capping bottles.
